Abstract

Water pollution caused by heavy metal mercury is a serious problem today. This study aims to utilise jackfruit wood waste as a natural adsorbent in overcoming the problem of water pollution due to heavy metal mercury. The methods in this research include jackfruit wood preparation, hydrochar synthesis through pyrolysis, hydrochar activation, wastewater preparation, batch adsorbent optimum conditions, and dynamic adsorption process (Fixed-Bed Column). The results showed that the optimum adsorption condition was reached at 0.4 M HCl concentration, pH 3 and 80minutes contact time. The study also showed that the adsorption kinetics followed a second-order pseudo model with a rate constant of 1.712 x 10-2 g/mg.min. The research data also showed conformity with the Langmuir isotherm model, with an adsorption capacity of 63.036 mg/g. The results of this study prove that jackfruit wood waste is effectively used as raw material for making activated carbon for wastewater treatment applications in removing heavy metal mercury.

Abstract

Cancer is one of the deadliest diseases in the world. Currently, there are various types of anticancer drugs that are used to treat cancer, but they still have various side effects that can interfere with the quality of life of patients. Organometallic complexes (OCOs) are chemical compounds consisting of metal atoms bonded to carbon atoms. OCOs have various potential to be used as anticancer drugs, including their ability to specifically target cancer cells, inhibit cancer cell growth, and reduce the side effects of other anticancer drugs. The mechanism of action of OCOs involves interactions with nucleophilic molecules within the cell, including DNA, RNA, and proteins, as well as the formation of additional platinum products. In this review, we will discuss organometallic compounds that can function as anticancer drugs, such as platinum, ruthenium, iron, carboplatin, and oxaliplatin, which have been shown to be effective in fighting cancer. We will also discuss the mechanism of action of these compounds in cancer cells and the types of cancer cells that can be treated with organometallic compounds.
